- generate AVAILABILITY manpage sections automatically - for consistent wording - allows us to double-check against other documumentation (symbols-in-versions etc) - enables proper automation/scripting based on this data - lots of them were wrong or missing in the manpages - several of them repeated (sometimes mismatching) backend support info Add test 1488 to verify "added-in" version numbers against symbols-in-versions.

NAME
CURLOPT_FTP_SSL_CCC - switch off SSL again with FTP after auth
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_SSL_CCC,
long how);
DESCRIPTION
If enabled, this option makes libcurl use CCC (Clear Command Channel). It shuts down the SSL/TLS layer after authenticating. The rest of the control channel communication remains unencrypted. This allows NAT routers to follow the FTP transaction. Pass a long using one of the values below
CURLFTPSSL_CCC_NONE
do not attempt to use CCC.
CURLFTPSSL_CCC_PASSIVE
Do not initiate the shutdown, but wait for the server to do it. Do not send a reply.
CURLFTPSSL_CCC_ACTIVE
Initiate the shutdown and wait for a reply.
DEFAULT
CURLFTPSSL_CCC_NONE
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt");
curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_CONTROL);
/* go back to clear-text FTP after authenticating */
curl_easy_setopt(curl, CURLOPT_FTP_SSL_CCC, (long)CURLFTPSSL_CCC_ACTIVE);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
